Saving Seeds You can customize your garden by saving seeds from the plants that you like best for their particular colour, size, shape or other qualities. Some annuals will reseed themselves if you let them bloom, die and drop their seeds to the ground. Most perennials, like chives and sunflowers do this all by themselves. When you decide which plants have seeds that you want to save you will have to let their flowers bloom and wither. This signals the plant to stop producing new buds so all of its energy will go into feeding the seeds developing on the stigma. If you want to save the seeds you need a bunch of small bags and envelopes. You’ll also need silica gel, which you can buy at a craft or hobby shop or a pharmacy. Before you use it, dry it in a warm oven and let it cool completely. Put about a teaspoonful (15 ml) into a small paper envelope. Use one with each envelope of seeds to keep them dry. You can also use the little bags that come with a pair of new shoes. Collecting Seeds This is the best way to separate and save specific colours for flowering plants like cosmos and calendulas. Once your chosen blooms have shrivelled and started to dry out remove the whole flower head. Let the blooms dry out completely and gently break them open over a small plastic or paper bag. Allow the seeds to dry out for a week or two. Store them in small envelopes labelled with the type of flower, what year it was saved and what colour the bloom was. Put the envelopes in airtight containers like Mason jars or freezer bags. Add a envelope of silica gel to each jar or bag to keep the seeds dry. Store your jars or envelopes in a shoebox in a cool, dry place. Don’t forget to label your boxes, too, so you’ll know what’s inside and when it was stored.
